| Abstract: | This paper discussed the methods for treating the boundary conditions of T steam turbine blade by finite element model analysis, analyzed the influence of various of the boundary conditions on the natural frequency of blade, and advanced the elastic computing model simulated the boundary conditions. The research showed the relationship between the boundary conditions and the blade natural frequency, and offered the theoretical foundation for the numerical study of blade model and failure analysis.
